The Serpent 401744 bladeless spool outdrives are engineered to tighten steering response and reduce component failures. Targeted at Project 4X and compatible with Eryx cars, these units dispense with the traditional driveshaft blade to lower breakage risk. Manufactured in high-strength spring steel, they are built for longevity with minimal material wear.
These outdrives are machined to achieve measured flexibility that absorbs impact forces without permanent distortion. The bladeless design reduces slack in the drive system, producing steadier turn-in and improved consistency lap after lap. Lower rotating mass also benefits acceleration out of corners.
Although designed with the Project 4X in mind, the spool outdrives also suit the Serpent Eryx range where the same spool interface is used. They are a practical choice for drivers who prioritise durability and repeatable handling when setting up for track conditions.
